What is the general opinion about recommended scrubber durations set by the experts/manufacturers. I was told yesterday when at a UK inland site that I could easily do 5 hours on my inspo and the bloke saying this could do 3 hours plus on his evolution. My personal feeling is to stay inside the set scrubber times and have done so for my 63 hours on my inspo with no signs of any problems, although he also recommends getting a co2 hit just so I know what it is like. I'd prefer to avoid that myself!
So, is this the general thought throughout Rebreather divers or just another plonker with too much money?

Never do anything your uncomfortable with or don't fully understand.
The how long will my scrubber last question is like how long is a piece of string.
If I add up sofnalime fill hours against in water hours the sofnalime is way ahead of me.
On saterday I spent an hour and a half in 6m of 13c water practicing for my cave course, and today i will be binning that fill before tomorrows 55m dive which will probably be two hours max due to the sea temp.
So a very conservative approach
On the other hand, when I was in the red sea I pushed 4-5hours on the scrubber doing a deep dive in the AM (70-100m) and a shallow dive in the PM 18-25m
Water temp 26c, no particular work involved during the dives, SACs well down around my normal 15 planning mark. Around 120bar of 02 used over the 4-5hours.
Basically about as easy as these sort of dives get.
So I was happy to push it a bit on the scrubber taking all the available information into consideration. Alterations in the temperature of the water depths and my workloads would have significant impact on these decisions.
In the UK the hardest i have pushed a scrubber was on my KISS at 195mins on one 70m dive. Obviously most of the time above 15m on deco.
